I have a 260z early. It weighs 2520 on a truck scale. It had all fluids and full tank of gas, rear tire, cheapo APC pepboys seats and an aftermarket AC installed. Its got a full interior also.

 

For comparison my 81 280zx 2+2 weighs 2600 with about 3/4 tank, all other fluids, no carpet no rear seats , no interior in the trunk area, no spare tire, and 2 sparco fighter seats. oh and no AC or AC lines.

My '72 with full interior, roll bar, 3/4 tank of gas, bigger wheels and tires, and a gnose weighs in at 2455.

 

Z-Ya and I own a 240 race car and with 8 gals of fuel, full dash, full cage, FG hood, fenders, air dam, lexan hatch window, gutted doors (no glass, no mechs, etc.),passenger seat weighs in at 2250. Car is stripped down right now being refreshed and a sheet metal dash will be installed but we will add a bar or two across this opening so I'm figuring no weight reduction. Hoping to get down to 2200 lbs.

That's not the curb weight, you know...

 

 

"GVWR" was just for added dramatic effect of the thread intro. Kinda like the first 6 seconds of a TV commercial.

According to the scales at San Antonio Dragway my 1976 2+2 with my 255# body inside it weighed in at 2695---seeing it runs 15.50 in the 1/4 at just under 90mph, that seems a reasonable engine power level for what I've done to it...

2245 w/o driver? Is it an early 260Z? What have you taken out of it?

 

The list of things left in it is shorter...

 

 

Lets see, it has no door carpet, no interior from the tail lights up to the seats. Gutted dash. I would suspect that the weight added with the turbo swap and the 16" wheels is more than the weight of everything I have removed. At least very close if you dont count the bumpers...forgot about those.

 

Ask someone that has gutted a S30 of all its interior panels, the interior of a Z is pretty light.

plastic and vinyl dont weigh that much....the tar and carpet on the floor is alot more than the plastic/vinyl...I am going to have to get my 81 280zx on the scales soon, ttop car, auto stuff still there (have 79 doors i will be putting on just for more weight savings if its not where i want it), NO dash, wiring taped to crash bar/run to cluster/triple gauge cluster, heater core/ac comp/lines/condensor/nothing that was under the dash just the wiring on the bar, extra brackets/junk in the engine bay that isnt needed,bumpers, single celica cloth seat, no tar on the floor/home depot carpet padding (lightweight multi-foam stuff) adhesive sprayed to the floor, NO interior pieces or door panels, no spare, header w/ 2 1/2" exhaust (still lighter than stock), all brackets/junk/etc on the bottom of the car is gone...still have a little more to go but i am hoping for 2k-2200 with me (140#) & gas in the car.

When my son and i gutted my 75 280Z for racing it weighed 2285 with the 2.8L 4 speed before the 5.0 swap. after the swap and before i started making it streetable again it was 2175. no interior at all, no dash, 1 gallon radiator, 1 seat, 8 gallon fuel cell. when we stripped the car the dash and heater assembly was over 325 by itself. My 23" x 13" wide slicks and wheels weigh less than the datsun tires and wheels at 28 lbs, my fronts, 20" x x9" are 22 lbs on steel wheels. All the interior plastic, carpet and pleather was over 250 lbs. But now i am having to put it all back in or fabricate it all.

Mine is still 99% stock. '71 240z, a couple gallons of gas, all other fluids topped up and heavy recaro knock off seats = 2330 lbs.

You're supposed to subtract your weight when you stand on a scale with parts in your hands :rolleyes::lol:

Last time I had mine on scales it was about 1983 lbs without driver, and with a couple gallons of gas, it had the full dash, but no interior plastics, all sound deadening removed, the seats replaced with Kirky aluminum shells, no side glass, rear glass replaced with plexy, and no lights.

 

It has no lights now, just brackets to hold some switches and gauges, the harness has been removed, and I ground off many of the now useless brackets for holding stock interior stuff. I need to get it on the scales again eventually to corner balance it.

Well I'm a bit confused about the numbers I just got... I just had my car scaled at a race shop and the total weight with a 180# driver in the driver's seat was 2909 and 12 gallons of fuel in the tank.

 

Here are the weights per corner:

 

Total: 2909lbs W/180# driver and 12 gallons fuel

 

LF 710 RF 690

LR 777 RR 732

 

My car is a 1976 280Z with zero sound deadening materials in it, Zero door hardware/ Glass, rear Lexan Hatch window, lexan 1/4 windows, Kirkey and Ultrashield aluminum seats, a sheet aluminum dash, no hvac system, and a Chevy V8 with all aluminum heads/intake/waterpump. I don't have any smog or emissions stuff. I have a 15 Gallon fuel cell in the car. The Battery, an optima Red Top sits behind the passenger seat in the rear floor. I do have a significant cage (1.5 inch DOM SCCA legal thickness tubing) in the car, along with Pete Paraska's 2X3 inch steel subframes. I have an aluminum radiator. I also have a Q45 rear diff/axles which are contributing to the weight. The wheel/tire combo is pretty head, as is the Mcleod Bellhousing on the setup. The V8 isn't picking up much weight if any over the L6 (We've seen 42# used as the number difference given my configuration). I do have an oil cooler/lines, and an accusump/lines, and a return line on the fuel system with a surge tank.

 

But based on what my guy told me, without anyone in the car, it's still well over 2700#. I questioned the weights, but he scales PCA club race cars, specmiatas, Spec944s... and other race cars... He seems to know what he is doing, and has set up my miata and Porsche for me without any issues or questions of his abilities in the past. The guy services and maintains all of CDOC's racecars/employee cars, and anyone who knows those folks knows they don't half-ass anything. So although I don't want to believe him... There's no reason not to. Is this car really that heavy? Ugh...

Mike, my z is within 50 lbs of yours [i'm 180 lbs]. Ls1, t56, alum rad, 6 pt autopower cage, stock fuel tank with atl black box, factory glass all around, corbeau seats, sound deadening [factory] there, q45 diff, 17" wheels and disc brakes. f-r distribution is 49-51 and cross weights are within a percent of each other. So, what are you and I doing wrong with our z's?! They seem to be about 200-300 lbs heavier than the others here.

I'm gonna weigh my car on Tuesday. I really think I will be in the 2300 lb range.

 

There's no ac, no heat, fully gutted interior, engine and chasis wiring tossed in garbage, car has bare minimum in engine harness and body, fuel cell, aluminum dash, fiberglass hood, no steel bumpers, and asr20 with side exit exhaust.

David, I don't know man... I'm just a little confused. My seats combined weight 36 pounds. My dash and gauges weigh maybe 15 pounds. My doors don't weigh more than 12 pounds each. My hood is carbon fiber and weighs nothing. No rear bumper or bumper hardware, the front bumper beind an MSA Type 3 airdam/bumper that weighs maybe 15 pounds.

 

Areas I know I can whittle down, tires/wheels are heavy and we have a solution in the works for that. The battery is heavy, so maybe a Braille unit could help... What else??? I know my cage is pretty substantial, but it's still only 1.5 inch SCCA legal tubing. The fuel cell is lighter than the stock fuel tank.

 

MrJDM, You might make that weight, but you likely may not. I got the numbers Thursday night and wanted to puke. I was expecting 2300-2500 pounds, but NOT 2700 pounds... No way in hell... Well... Here I am... 2700 pounds.

 

Here's what I know... I have the means, and if need be, I'll gutt the cage and start over on the car. This car WILL lose the weight... I've lost 30 pounds in three months, and I'll lose another 30 over the fall/winter... The car has got to shed pounds if I'm going to enter it in anything worth doing with it.

By the way, this is a very handy little corner weight calculator...

 

http://opuscorvair.com/cornerweightcalculator.html

 

My cross corner weights are pretty decent at 48.5%, and the front to rear is really good ... 48.2 front/51.8! Even if she is a heavy pig!!!

Cooll link Mike-here are my results.

 

· Weight [1/2 tank gas] 2769

 

· Total wt 2944; front:1451, rear:1493 [including 175# driver]

 

· Corner wt w/175# driver; 754 LF, 747 LR, 703 RF, 740 RR

 

· f/r weight distribution 49.49 / 50.509

 

· cross weights 50.7% lf / rr, 49.3 rf / lr

 

With a cross weight of >48.5%, you have what is considered to be a TIGHT race car.

 

 

 

Just added power windows so it may have gained a bit of weight, perhaps once the long tubes are completed and installed it'll offset that gain or I may have to install a little cam...
